    • Application Ion-Plated Cr-Tin Multilayer Coating To Steam Turbine Blades. 
      Ebara, Ryuichio; Nakajima, Hiroshi; Odohira, Toshihiko; Wada, Tetsuyoshi; Hatano, Masaaki (Texas A&M University. Turbomachinery Laboratories, 1987)
      In order to apply a recently developed ion-plated coatings to compressor driving steam turbine blades, cavitation erosion tests were conducted to select the effective multilayer coating to prevent drain erosion of the ...
    • Compressor Performance Modelling And Monitoring. 
      Duggan, John B. (Ben) (Texas A&M University. Turbomachinery Laboratories, 1987)
      One of Du Pont's plants operates a 20,000 hp synchronous motor driven process air compressor consisting offour compression sections and three intercoolers (Figure 1). A six percent capacity increase from refitting the first ...
    • Conversion Of A 19,000 HP Propylene Compressor Drive From Steam Turbine To Electric Motor With Geared Cariable Speed Turbo Coupling. 
      Henschel, Franz-Klaus; Rappold, Walter (Texas A&M University. Turbomachinery Laboratories, 1987)
      In the course of modernizing an ethylene plant in 1985, Union Rheinische Braunkohlen Kraftstoff AG converted a propylene compressor with 4 process stages from a steam turbine drive to an electric motor drive. The economic ...
    • Electric Shaft Currents In Turbomachinery. 
      Vance, John M.; Palazzolo, Alan B.; Zeidan, Fouad Y. (Texas A&M University. Turbomachinery Laboratories, 1987)
      Electrical damage to turbomachinery parts has caused a number of machinery failures and many hours of costly downtime. The problem of electrical voltages and currents being generated in non-electrical machines has puzzled ...
    • Experience With Periodic Vibration Monitoring In Fossil Power Stations. 
      Piety, Kenneth R.; Pardue, E. Forrest; Phillips, Ernest P. (Texas A&M University. Turbomachinery Laboratories, 1987)
      Results are presented from data obtained from the cumulative experience of eight utilities which are conducting periodic, computer based predictive maintenance (PM) programs at their fossil stations. These programs are ...
    • Major Revamp And Retrofit Of Identical Process Compressor Trains. 
      Low, M. Donald; Nemec, Richard E. (Texas A&M University. Turbomachinery Laboratories, 1987)
      Major uprates of process compressor train performance can be achieved utilizing the existing machinery. The following is a broad overview of a project to revamp two identical compressor trains to achieve levels well over ...
    • New Solutions In The Process Industry - Application Of Six-Stage Integrally Geared Centrifugal Compressors. 
      Rothstein, Ernst (Texas A&M University. Turbomachinery Laboratories, 1987)
      At the end of the forties, the integrally geared centrifugal compressor was developed and initially used for air, and later for nitrogen and other gases. To date, about 10,000 units are in use working in the capacity range ...
    • Retrofit Of Gas Lubricated Face Seals In A Centrifugal Compressor. 
      Kocur, John A.; Platt, John P.; Shabi, Larry G. (Texas A&M University. Turbomachinery Laboratories, 1987)
      There are significant advantages in using gas lubricated face seals (dry gas seals) in centrifugal compressor service. Foremost among these are the elimination of the seal oil system resulting in lower maintenance, increased ...
    • Retrofitting Gas Turbines With Computer Control. 
      Taub, Joel R.; Armacost, Joseph E. (Texas A&M University. Turbomachinery Laboratories, 1987)
      Retrofitting gas turbines with microprocessor based controls has improved reliability and performance in the areas of speed control, temperature control, and load control. The rationale behind control system retrofits is ...
    • Revamp Of Turbocompressors. 
      Aicher, Walter; Schnyder, Samuel (Texas A&M University. Turbomachinery Laboratories, 1987)
      The rerating possibilities of compressors are discussed. Starting from the characteristic equations for design purposes, the relevant design parameters are specified. Concerning the rerating of axial compressors, methods ...
    • Revamping The Air Compressor In An Ammonia Plant. 
      Hoppock, William G.; Fisher, Larry L. (Texas A&M University. Turbomachinery Laboratories, 1987)
      Revamping the compression equipment in an ammonia plant can help optimize plant output and improve overall efficiency. In this case, proper sizing of the revamp is important for optimum results. The reformer air compressor ...
    • Subsynchronous Vibration Problem And Solution In Multistage Centrifugal Compressor. 
      Allaire, Paul E.; Stroh, Carrol G.; Flack, Ronald D.; Kocur, John A.; Barrett, Lloyd E. (Texas A&M University. Turbomachinery Laboratories, 1987)
      The investigation of a subsynchronous vibration problem encountered in a six stage centrifugal compressor is discussed. At a running speed of approximately 9000 rpm, a subsynchronous vibration (at 4200 rpm) of nearly two ...
